a study to learn how different amounts of pf-06954522 are tolerated and act in adults with type 2 diabetes mellitus

Conditions: Type 2 Diabetes Mellitus (T2DM); Obesity

Summary: the purpose of the study is to evaluate the safety, tolerability, pharmacokinetics (pk) and pharmacodynamics (pd) of multiple escalating oral doses of pf-06954522 in adult participants with inadequately controlled type 2 diabetes mellitus (t2dm) on metformin (part a) and optionally in non-diabetic participants with obesity (part b).

positive testing for hiv, hbsag, or hcvab. hepatitis b vaccination is allowed. * diagnosis of type 1 diabetes mellitus or secondary forms of diabetes. * parts b and c only: participants enrolling as non-diabetic with obesity (part b) or healthy (part c) may not have medical history of t2dm. * evidence or history of clinically significant cardiovascular disease. in particular, history of myocardial infarction, unstable angina, arterial revascularization, stroke, new york heart association functional class ii iv heart failure, or transient ischemic attack within 6 months of screening. * any malignancy not considered cured (except basal cell carcinoma and squamous cell carcinoma of the skin); a participant is considered cured if there has been no evidence of cancer recurrence in the previous 5 years. * acute pancreatitis or history of chronic pancreatitis. * acute gallbladder disease. * parts a and b only: a response of 'yes' to question 4 or 5 or on any behavioral question on the c-ssrs at screening or day -1 in the study. in addition, participants deemed by the investigator to be at significant risk of suicidal or violent behavior should be excluded. * personal or family history of mtc or men2, or participants with suspected mtc per the investigator's judgement. * any medical or psychiatric condition including recent (within the past year) history of: suicidal ideation/behavior, major depressive disorder, schizophrenia, bipolar disorder; or laboratory abnormality or other conditions that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study * use of prescription or nonprescription drugs and dietary and herbal supplements that are bcrp, mdr1/p-gp, or oatp inhibitors is prohibited within 14 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention; use of moderate or strong inhibitors or inducers of cyp3a, ugt1a1, or ugt1a3 is prohibited within 14 days plus 5 half-lives prior to the first dose of study intervention. * part a and b: use of certain concomitant medication that are unlikely to interfere with the study results may be allowed. however, use of prescription or nonprescription drugs and dietary and herbal supplements that are sensitive cyp1a2, cyp2c19, cyp3a, bcrp, mdr1/p-gp, oatp1b3, or ugt1a1 substrates is prohibited post day -1. * part c: use of moderate or strong inhibitors or inducers of cyp2c19 are prohibited within 14 days plus 5 half-lives prior to the first dose of study intervention. use of all other prescription or nonprescription drugs and dietary and herbal supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention. * use of any prohibited prior/concomitant medication(s) or participant unwilling or unable to use a required concomitant medication(s). * previous administration of an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of study intervention used in this study (whichever is longer). * known prior participation (ie, randomized and received at least 1 dose of study intervention) in a trial involving pf-06954522. note that a given individual may only participate in a single cohort of this study. * a positive urine drug screen at screening or admission. participants who have been medically prescribed benzodiazepines and report the use of these drugs to the investigator at the screening visit may be allowed to participate if approved by the sponsor. * parts a and b only: screening supine bp ≥160 mm hg (systolic) or ≥100 mm hg (diastolic) following at least 5 minutes of supine rest. if bp is ≥160 mm hg (systolic) or ≥100 mm hg (diastolic), the bp should be repeated 2 more times and the average of the 3 bp values should be used to determine the participant's eligibility. part c only: screening supine bp ≥140 mm hg (systolic) or ≥90 mm hg (diastolic) for participants \<60 years; and ≥150/90 mm/hg for participants ≥60 years old, following at least 5 minutes of supine rest. if systolic bp is ≥140 or 150 mm hg (based on age) or diastolic ≥90 mm hg, the bp should be repeated 2 more times and the average of the 3 bp values should be used to determine the participant's eligibility. - screening 12-lead ecg that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results (eg, baseline qtcf interval \>450 ms, complete left bundle branch block, signs of an acute or indeterminate age myocardial infarction, st-t interval changes suggestive of myocardial ischemia, second- or third- degree atrioventricular block, or serious bradyarrhythmias or tachyarrhythmias). if qtcf exceeds 450 ms, or qrs exceeds 120 ms, the ecg should be repeated 2 more times and the average of the 3 qtcf or qrs values should be used to determine the participant's eligibility. computer interpreted ecgs should be overread by a physician experienced in reading ecgs before excluding participants. * participants with any of the following abnormalities in clinical laboratory tests at screening, as assessed by the study-specific laboratory and confirmed by a single repeat test if deemed necessary: * ast or alt level ≥1.5 × uln; * total bilirubin level ≥1.5 × uln; participants with an elevated total bilirubin consistent with gilbert's disease will have a direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is ≤uln; * tsh \> uln; * fasting c-peptide \<0.8 ng/ml; * serum calcitonin \> uln; * amylase \> uln; * lipase \> uln. * fasting blood glucose * part a only: \>270 mg/dl at screening or admission, confirmed by a single repeat test if deemed necessary. * parts b and c only: \>126 mg/dl at screening or admission, confirmed by a single repeat test if deemed necessary. * renal impairment as defined by an egfr \<75 ml/min/1.73m2. confirmation of screening egfr by a single repeat test is permitted, if deemed necessary. • based upon participant age at screening, egfr is calculated using the recommended ckd-epi equations in section 10.7.2 to determine eligibility (screat-based formula). * history of alcohol abuse or binge drinking and/or any illicit drug use or dependence within 6 months of screening. binge drinking is defined as a pattern of 5 (male) and 4 (female) or more alcoholic drinks in about 2 hours. as a general rule, alcohol intake should not exceed 14 units per week (1 unit = 8 ounces (\[240 ml\] beer, 1 ounce \[30 ml\] of 40% spirit or 3 ounces \[90 ml\] of wine). * prior use of a glp-1r agonist within 6 months prior to screening or known intolerance to any glp-1r agonist. * body weight exceeds the maximum capacity of the site's body weight scale, preventing accurate assessment of body weight. * part c only: history of hypersensitivity, intolerance, or allergic reaction associated with prior exposure to rosuvastatin, midazolam, or omeprazole. * part c only: use of tobacco/nicotine containing products in excess of the equivalent of 5 cigarettes/day or 2 chews of tobacco/day. * investigator site staff directly involved in the conduct of the study and their family members, site staff otherwise supervised by the investigator, and sponsor and sponsor delegate employees directly involved in the conduct of the study and their family members.
